EDWIN S. JOHNSTON AND WILSON F. MYERS, 0F MOUNT VERNON, IOWA.

BROODEIR.

Application filed May 23, 1913.

7 '0 all whom it may concern Be it known that we, EDWIN S. JOHNSTON and Wrnsov F. MYERS, citizens of the United States, and residing at Mount Vernon, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Brooders, of which the following is a specification.

This invention relates to certain new and useful improvements in brooders, and more particularly to that class designed to be heated by hot air.

An object of the invention is to provide a brooder which is extremely simple in construction, and inexpensive to manufacture, the several parts forming the same being readily assembled and liability of the same becoming damaged greatly reduced.

lVith the above and other objects in view, the invention will be more fully described in detail, reference being had to the accompanying drawings by corresponding numerals throughout the several views, in which:

Figure 1 is a perspective view of the brooder. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a view partly in section taken on the line a:--m of Fig. 2, and, Fig. 4 is an enlarged side elevation of the lamp and its supporting means.

Referring more particularly to the drawing, the reference numeral 10 indicates the top wall of the hover, which is preferably circular and has depending therefrom the annular side wall 11. Any number of supporting legs 12 are provided so that the lower edge of the side wall 11 is disposed entirely above the floor or other support. The top wall 10 is provided with a central opening 13, the object of which will pres ently be described. A fabric band or strip l-il is secured in any suitable manner to the bottom edge of the side wall 11 and is of a length in depending therefrom to substantially reach the floor or other support upon which the brooder may be mounted. The strip 14: is provided with spaced slits affording depending tabs 15 to present a ready entrance and exit for the chicks.

The heating means for the brooder consists of a vertical tubular member 15 closed at its bottom as at 16 and open at its upper end. A series of perforations 17 are provided in the member 15' adjacent the bottom end 16. Disposed adjacent the under side of the top wall 10 of the hover, is a coiled heating tube 18 having its inner end open- Specification of Letters Patent.

ing into the member 15 as at 19, while the other end thereof is continued outwardly to the side wall 11 and formed into an upwardly directed outlet 20 extending through the top wall 10.

The lamp and its supporting means comprises a lamp 21 of usual construction provided with an annular flange 22 extending beyond the side wall of the oil cup. Supporting rods 23 are connected at their lower ends to the flange 22 and carry upon the upper ends thereof a cover plate 24; provided with a handle 25. The rods 23 adjacent their lower ends are outwardly bent as at 26, the bends extending laterally beyond the flange 22.

In assembling the several parts, the heating coil 18 is placed within the hover and preferably suitably secured to the under face of the top 10, the upper end of the tubular member being also suitably secured to said top 10. hen it is desired to heat the hover, the lamp is lighted, and lowered into the tubular member 15, the bends 26 serving to guide the same therein, and when completely received within said member, the cover plate 21 closes the upper end of member 15 and prevents the heat from escaping. Air for combustion of the lamp is admitted through the perforations 17 to the tubular member 15. Therefore, the heat from the lamp 21 contained within the member 15 passes therefrom into the heating coil 18, circulates therethrough and finds its exit through the outlet 20. It will be noted that the lamp 21 and annular flange 22 are of smaller diameter than the tubular member 15 which permits a ready circulation of air thereabout to provide for complete combustion. By such construction all heating means is spaced from the support and all liability of the chicks becoming burnt or otherwise injured is obviated.

lVhile we have shown and described in detail the preferred embodiment of our invention, we do not wish to limit ourselves tl1ereto, as various forms and modifications may be had which will fall within the scope of the invention as claimed.

Having fully described our invention, what we claim as new is:-

In a hover, a tubular member arranged centrally thereof, said tubular member being open at its upper end and closed at its lower end and constituting the major supportin means for the hover, a heating coil fixed Q miaaso to the under side of the top Wall of the the open upper end of said member, said hover, the inner end of said coil entering means engaging the tubular member to rensaid tubular member at its upper end and der the same stable.

having its outer end extending through .the In testimony whereof We aiiix our signa- 5 top Wall of the hover adjacent the outer tures in presence of two Witnesses.
